What is a timing light?
and why might you need one
A timing light is a device that allows you to see when engine ingnition is taking place in relation to the position of the piston (normally the first piston in an engine block).
Why is this important?
Peak engine power and efficiency are critically related to timing of the ignition, if the spark plug fires too soon or too late (too advanced or retarded) your engine will not be running as effectively as it could, it may even not run at all or if it does then wear and fuel use could be increased along with emissions.
This is a great video showing all aspects of engine timing and adjustment.
